AMD Radeon RX 6600 XT Launching For 1080p RDNA2 Gaming At ~$379 USD

AMD just lifted the embargo on the Radeon RX 6600 XT, its newest entry in their RDNA2 line-up and optimized for delivering a superior 1080p gaming performance against the NVIDIA GeForce RTX 3060 series. The RX 6600 XT isn’t hitting retail availability until August and that is when we’ll be able to publish benchmarks, but for now here is an overview of this new graphics card launching at the $379 price point.

The Radeon RX 6600 XT graphics card features 32 compute units, 8GB of GDDR6 video memory, a 32MB infinity cache, and a 2359MHz game clock. This RDNA2 graphics card has a 160 Watt TDP and thus requires just a single 8-pin PCIe power connector. During AMD’s press briefing on the RX 6600 XT it was brought up repeatedly that the focus of the RX 6600 XT is on delivering a superb 1080p gaming experience.

Given the continuing popularity of the GeForce GTX 1060 graphics card, AMD referred to the RX 6600 XT as delivering up to 2.5x more performance. Or gen over gen, the RX 6600 XT is 1.4~1.7x faster than the RX 5600 XT or RX 5700 Navi cards.

AMD’s Windows-based figures put the Radeon RX 6600 XT at roughly up to 15% faster on average than the GeForce RTX 3060. It will be interesting though to see how the performance compares under Linux once getting our hands on the card and being able to share those performance numbers.

Perhaps the biggest surprise of the Radeon RX 6600 XT presentation was the price… $379 USD for this 1080p focused card. Back in the day, the GeForce GTX 1060 launched at $250 USD. Or even just a generation ago the RX 5600 XT pricing started out at around $280 USD. AMD acknowledged that this suggested retail pricing on the RX 6600 XT is driven by the current market conditions and they opted for setting a realistic price versus putting an artificially lower price knowing full well the prices for what other graphics cards are commanding these days and retailers would likely otherwise mark-up the card pricing themselves. AMD will be monitoring the market conditions and will be adjusting accordingly. They are also working on ensuring there is sufficient supply of the Radeon RX 6600 XT, but we’ll see how that goes once these cards launch in August. AMD isn’t releasing a reference card of the RX 6600 XT but relying on their AIB partners.

Stay tuned for our plethora of Linux benchmarks of the AMD Radeon RX 6600 XT starting 11 August.

Open-Source Radeon Tools Updated With Expanded RDNA(2) Support, Other Features


In addition to NVIDIA releasing new open-source GameWorks projects this week for the Game Developers Conference, AMD with their GPUOpen initiative has released several updated Radeon Windows/Linux tools.

Radeon GPU Analyzer 2.5 is out today with expanded RDNA2 support (GFX1032 target support), support for analyzing OpenCL on RDNA/RDNA2/CDNA targets, live VGPR analysis and control-flow graph support within the Vulkan path, and a variety of other bug fixes and improvements to this graphics analyzer.

Radeon Memory Visualizer 1.2 is also out with stability and bug fixes, tooltips to supply more information, and range-based address search for resource tables.

Radeon GPU Profiler 1.11 was also released today. Radeon GPU Profiler 1.11 brings support for additional RDNA2 GPUs, cache counter support for OpenCL applications, ray-tracing handling improvements, faster loading of profiles, and other changes.

Details on these update tools and the other open-source Radeon packages for developers via GPUOpen.com.

GFX1013 Target Added To LLVM 13.0 For RDNA2 APUs


Merged last week to mainline LLVM 13.0 was the new “GFX1013” target for the AMDGPU shader compiler. Well, it landed twice as at first had to be reverted after breaking the build bots / sanitizer testing.

GFX1013 is the newest graphics target for AMDGPU LLVM. Notable out of the commit is confirmation that it’s for an RDNA2-based APU. Like with the other RDNA2 GPUs, the compiler target does confirm that GFX1013 does feature ray-tracing support with the BVH ray-tracing instructions being present.

Current rumors put the Ryzen 6000 series APUs as featuring Zen 3 (or Zen 3+) CPU cores with RDNA2 graphics. These “Rembrandt” APUs are also expected to launch with DDR5 memory support. Some more recent rumors put the Rembrandt APUs as having up to 12 CUs. In any case it will be great to see AMD APUs coming with RDNA2 in moving beyond Vega graphics.

The LLVM 13.0 compiler stack should be out as stable in September while waiting for the rest of the open-source AMD Radeon Linux graphics stack to get ironed out for AMD’s next-gen APUs.
